CAUTION
Failure to use an ATX12V power supply, or not connecting the additional power supply lead to the Desktop Board D850EMD2 or D850EMV2 may result in damage to the desktop board and/or power supply.
The desktop boards support a single Intel Pentium 4 processor. Processors are not included with the desktop board and must be purchased separately.
The processor connects to the desktop board through the mPGA 478-pin socket. The Pentium 4 processor may be removed and replaced to accommodate supported higher speed processors.
For instructions on how to install a processor, see Chapter 2 on page 21.
The desktop boards support the processors listed in Table 2.

BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub. The BIOS can be updated by following the instructions in Chapter 3 on page 35.
PCI Auto Configuration
If you install a PCI add-in card in your computer, the PCI auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI add-in card.
15
Intel Desktop Boards D850EMD2 and D850EMV2 Product Guide
IDE Auto Configuration
If you install an IDE device (such as a hard drive) in your computer, the IDE auto-configuration utility in the BIOS automatically detects and configures the device for your computer. You do not need to run the BIOS Setup program after installing an IDE device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program.
To use ATA-66/100 features, the following items are required:
•An ATA-66/100 peripheral device
•An ATA-66/100 compatible cable
•ATA-66/100 operating system device drivers
Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the Setup and for booting the computer, with the following restrictions:
•The supervisor password gives unrestricted access to view and change all Setup options. If only the supervisor password is set, pressing <Enter> at the password prompt of Setup gives the user restricted access to Setup.
•If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered.
•Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer.

17
Intel Desktop Boards D850EMD2 and D850EMV2 Product Guide
Instantly Available Technology
CAUTION
For Instantly Available technology, the 5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or affect ACPI S3 sleep state functionality.
CAUTION
If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the desktop board may lose register settings stored in memory.
Instantly Available technology enables the desktop board to enter the ACPI S3 (Suspend-to-RAM) sleep state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up device or event, the system quickly returns to its last known awake state.
The desktop board’s standby power indicator, shown in Figure 3 on page 18, is lit when there is standby power to the system. This includes the memory modules and PCI bus connectors even when the computer appears to be off.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber.
